Hey everyone

Just wondered if anybody knew when this is supposed to be changed?

Also what the part number for the oil is that vauxhall use?

I got my 40k service coming up soon and all cambelt etc. are being done but thought i'd ask if thats supposed to be changed at the same time. I already have two brand new unopened containers of gearbox oil from vaux from my 1.6 sxi which I never got round to doing before selling it but didnt know if its the same stuff.

Hope someone knows.
